All Known Implementing Classes:: DOMImplementationImpl

public interface DOMImplementation

The DOMImplementation interface provides a number of methods for performing operations that are independent of any particular instance of the document object model.

Method Summary

Document createDocument(java.lang.String namespaceURI, java.lang.String qualifiedName, DocumentType doctype)
          Creates an XML Document object of the specified type with its document element.

DocumentType createDocumentType(java.lang.String qualifiedName, java.lang.String publicId, java.lang.String systemId)
          Creates an empty DocumentType node.

boolean hasFeature(java.lang.String feature, java.lang.String version)
          Test if the DOM implementation implements a specific feature.

Method Detail

hasFeature

public boolean hasFeature(java.lang.String feature,
                          java.lang.String version)

Test if the DOM implementation implements a specific feature.

Parameters:: featureThe - name of the feature to test (case-insensitive). The values used by DOM features are defined throughout the DOM Level 2 specifications and listed in the section. The name must be an XML name. To avoid possible conflicts, as a convention, names referring to features defined outside the DOM specification should be made unique by reversing the name of the Internet domain name of the person (or the organization that the person belongs to) who defines the feature, component by component, and using this as a prefix. For instance, the W3C SVG Working Group defines the feature "org.w3c.dom.svg".; versionThis - is the version number of the feature to test. In Level 2, the string can be either "2.0" or "1.0". If the version is not specified, supporting any version of the feature causes the method to return true.
Returns:: true if the feature is implemented in the specified version, false otherwise.

createDocumentType

public DocumentType createDocumentType(java.lang.String qualifiedName,
                                       java.lang.String publicId,
                                       java.lang.String systemId)
                                throws DOMException

Creates an empty DocumentType node. Entity declarations and notations are not made available. Entity reference expansions and default attribute additions do not occur. It is expected that a future version of the DOM will provide a way for populating a DocumentType.
HTML-only DOM implementations do not need to implement this method.

Parameters:: qualifiedNameThe - qualified name of the document type to be created.; publicIdThe - external subset public identifier.; systemIdThe - external subset system identifier.
Returns:: A new DocumentType node with Node.ownerDocument set to null.
Throws:: DOMException - INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName is malformed.
Since:: DOM Level 2

createDocument

public Document createDocument(java.lang.String namespaceURI,
                               java.lang.String qualifiedName,
                               DocumentType doctype)
                        throws DOMException

Creates an XML Document object of the specified type with its document element. HTML-only DOM implementations do not need to implement this method.

Parameters:: namespaceURIThe - namespace URI of the document element to create.; qualifiedNameThe - qualified name of the document element to be created.; doctypeThe - type of document to be created or null. When doctype is not null, its Node.ownerDocument attribute is set to the document being created.
Returns:: A new Document object.
Throws:: DOMException - INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName is malformed, if the qualifiedName has a prefix and the namespaceURI is null, or if the namespaceURI is different from " http://www.w3.org/XML/1998/namespace" .
WRONG_DOCUMENT_ERR: Raised if doctype has already been used with a different document or was created from a different implementation.
Since:: DOM Level 2
